Application filed January l0, 1916.

To @ZZ whom t 71mg/ concern.'

Be it known that l, Hanni' GORDON Curr', a subject of the King of GreatBritain, and a resident of the city of Hamilton, in the county ofVVentworth, Province of Ontario, Dominion of Canada, have inventedcertain new and useful Improvements in Steel Cupboards, of which thefollowing is a specification.

My invention relates to improvements in steel cupboards and the objectof' the invention is to devise a cupboard capable of being knocked down,in compact form for easy shipment and it consists essentially ofinterengaging side, rear and top and bottom portions, a door sashcomprising side and top and bottom portions secured to the top, bottomand sides of the cupboard and interlocking one with the other, andsliding doors held in grooves in the sash, the parts being arranged ashereinafter more particularly explained by the following specification.

Figure 1 is a general perspective viev.T of my cupboard. Fig. 2 is avertical section through my cupboard. F ig. 3 is a section through Fig.2 along the line mkg/ F ig. 1 is an enlarged detail of the door sash,the members being broken away intermediate of their length. Fig. 5 is anenlarged perspective View of my handle. F ig. 6 is an en# largedhorizontal section through my handle. Fig. 7 is an enlarged detail of'my angle bracket.

1n the dra-Wings like letters of reference indicate corresponding partsin each ligure.

1 indicates the floor of the cupboard provided With upwardly extendingsurrounding flanges 2. 3 indicates the side Walls provided With aventilator 3X and With inwardly extending flanges 4. 5 indicates a backWall provided with inwardly extending flanges 6. 7 indicates the topprovided With a surrounding flange 8. 9 indicates angle brackets securedto the back Wall portion 5 and to flanges 6 thereof. 10 indicates thedoor sash comprising the vertical side portions 101 and 102 and the topand bottom portions 103 and 104. 11 indicates a reduced portion of thetop portion 103 interengaging With the upper ends of the side portions101 and 102 to form a dovetailed jamb. 11X indicates a reduced portionof the bottom portion 104 interengaging with the loiver ends of the sideportions 101 and 102 to form a dovetailed jamb. 12 and 12X indicategrooves in the portions 101, 102 10p and 101 of the sash 10.

13 indicates a door slidino' in the groove 12 and provided With abent-in portion 13X. 141 indicates a door sliding in the groove 12X andprovided with a bent-out portion 11X. 15 indicates the horizontal traysupporting members pivoted to the sash dovvnturned portions 15X adaptedto engage with the angle brackets 9. 16 indicates a handle provided withan extending portion 17. 18 indicates bolts secured to the doors 18 and14 respectively and passing through the slotted hole 19 of the handle16. 9,0 indi- CatesI a hole in the sash 10 adjacent to the groovedportions 12 and 12X of the sash 10 provided for a purpose hereinafterdescribed.

Having described the principal parts involved in my invention 1 willbriefly describe the manner in which it is put together.

The base portion 1 is placed in the horizontal position and the sideportions 3 placed vertically on the base 1 and against the upwardlyextending portions 2. The back portion 5 is then placed vertically onthe base 1 to lit inside the flanges of the side portions 3. The doorsash 10 assembled with the portions 11 dovetailing With the upper endsof the portions 101 and 102 and with tae portions 11X dovetailing withthe lower ends of the portions 101 and 102 is then placed vertically inposition fitting into the angles formed by the side Walls 3 and theextending flanges 1 thereof. Then by turning down the pivoted traysupporting members 15 so that the portions 15X thereof engage With theangle brackets 9, the side portions 3*, the back portion 5 and the sash10 are securely tied together. The sliding' doors 11 and 13 are theninserted in the grooves 12X and 12 respectively and the door 11 is keptin its position by sliding' the handles 16 so that the extendingportions 17 thereof engage with the holes 20 of the sash 10. ln order tolower the door 14 the handles are first pulled toward each other, so asto disengage the portions 17 from the then the door may be lowered. door13 is kept down so that portion 13X presses tightly of the door 11 bythe of its handles eng'agsash similar to the Similarly the its extendingagainst the portion 14X extending portions 17 ing With holes in theholes 20 shown in the door 14. The door 13 may be kept in the raised oropen position by the portion 17 of the handle engaging With the upperholes 20.

10 and havingl The top 7 is then placed so that its flanges 8 surroundthe upper extremities of the members 3, 4t, and 10.

Hence it will be seen that l have devised a simple detachable cupboardin which the parts are securely tied together' and in which no bolts orsupplemental devices other than that connected with the parts themselvesare used, consequently no tools are used for erecting or knocking down.

Vhat l. claim as my invention is:
